Upper Crankshaft Bearing Identification





Arrow points in direction of travel

From the factory, the upper bearing shells are allocated to the cylinder block with the correct thickness. Colored spots serve to identify the bearing thicknesses.

The letters marked on the lower sealing surface of the cylinder block identify which bearing thickness must be installed in which location.





If color markings can no longer be read, use the blue bearing shell.

The lower crankshaft bearing shells are always shipped as replacement part with "yellow" color marking.
